[josm-dev] Automatically activate ImageryProvider for current area?

[Dr. Tilmann Bubeck]

Hello!

JOSM already includes a large number of imagery providers. Some of them  
are activated by default, but most are not.

I would like to improve JOSM to automatically activate (or deactivate) all  
imagery providers which are available for the current area, which the user  
is editing. E.g. if I am editing "munich" which is part of "bavaria", then  
the imagery provider "Bavaria (2m)" would be activated after downloading  
the area. The file "http://josm.sourceforge.de/maps" already includes the  
bounding boxes of the different imagery providers, so checking an provider  
for a selected area is possible...

This would improve quality of the user edits, because they see all imagery  
providers which are available. (I was using JOSM by myself for quiet a  
long time until I started discovering the various menu entries and found,  
that there are more (and better) imagery providers, than standard BING for  
"my" areas).

One could even extend that idea and sort all activated imagery providers.  
The one which is of highest speciality (=smallest surrounding area) is  
considered the "best" and is automatically selected (and not only  
activated). So If you assume, that there are imagery providers for  
"munich", "bavaria" and "germany", and I am editing "munich", then they  
will be sorted: 1. munich, 2. bavaria, 3. germany and munich is selected.

What do you think of that idea? I am willing to develop a patch for  
inclusion, if you like that idea. Feel free to discuss!

Kind regards,
   Tilmann Bubeck
